json: Remove invalid typedef redefinition
The C standard does not allow for typedef redefinitions, even if they map to the same underlying type. In order to avoid including the jsmn.h in json.h and thus exposing jsmn's internals, we have exactly such a forward-declaring typedef in json.h. If enforcing the GNU99 C standard, clang may generate a warning about this non-standard construct. Fix the issue by using a simple "struct jsmntok" forward declaration instead of using a typedef.
